For skewed right mean is greater than median
WebIn a positively skewed distribution, the mean is greater than the median as the data is more towards the lower side and the mean average of all the values. In contrast, the median is the middle value of the data. So, if the data is more bent towards the lower side, the average will be more than the middle value.
